ELECTRIC LAMP AND SUPPORTING-BRACKET THEREFOR.

Specification of Letters Patent.

Patented 0013.1, 1912.

Application filed August 21, 1912. Serial No. 716,153. l

To all whom' it may concern:

Be it known thatl, GORDON VViLLrAMs, a citizen of the United States, residing at New Haven, inthe county of New Haven 'and State of Connecticut, have invented a new and iisefnl lmprovementfin Electric Lamps and Supporting-Brackets Therefor; and l do hereby declare the following, when taken in -connection with the accompanying drawings and the characters of reterence'marked thereon, to be a full', clear, and exact description of the' same, and which said drawings constitute part of this application, and .represent, in

Figure l a' 'side View of anelectric lamp and supporting bracket therefor, constructed in accordance `with my invention.' Fig'. 2 a top view of the same. Fig. 3a broken view in vertical section oftheupper portion of the lamp body and outer end. of

the bracket showingi electrical connections` between them.

This invention relates to an improvement in electric lamps and supporting brackets therefor, and particularly to electric lam'ps for vehicles in which one pole of the circuit' is made through the'lalnp 'body and supporting bracket, and the other by a wire leading through the bracket, and is animprovement on the invention shown and described in Letters. Eatent of the United States No. 1,030,955 granted July "ist, 1912.

llminy prior patent, while one pole of the circuit i as made through the body of the lamp and'supporting bracket therefor, it was necessary to employ a wire leading from the lam to the bracket.

The o ject of this invention is to make the connection more directly with the lamp and avoid wiring the lamp body; and the invention consists in the construction hereinafter described and particularly recited in the claims.

in carrying out my invention, l employ a lamp-body 2 of any approved design providednear itstop with a socket plate 3 cary i r ing a socket t adapted to be passed overt e horizontal arm 5 of' a supporting bracket. Entered through the socket is a set screw 6 for clamping the lamp to the bracket. Extending through the horizontal arm 5 is a longitudinal hole 7 formed in its outer end with a chamber 8 to receive an inling through it,'a contact pin mounted in the sulating block 9. In this block is a metal bushing 10 to the rear end of which'a wire 11 is attached, this wire leading through thebracket to a battery, not shown.` In the outer end of the bushing is a sprin opei' ated pin l2 which normally projects' eyond the end of an insulating block 9', and is adapted to strike one side of asleeve 13 lsecured in the top of a lamp'from which it is Iinsulated by a block 14,- this block 14 containing a centrally arranged metallic housing 15 electrically connected with the sleeve by a screw 1G or otherwise, and containing a spring pin 17 making contact" with one pole fthe lamp, the other pole, asl before stated,

em brac (et, and vthence through other metal portions of the vehicleto which the bracket is attached. It will be understood without illustration,

that the top of the lamp body may 'be finished with any suitable ornamental'cap to inclose the upper end.

The lamp is supported on the bracket, and

when passed onto the horizontal` arm to a suiiicient extent, the spring pin 12 will come to a bearing against the sleeve 13"a-nd so 80 close the circuit through the lamp.

l.' lin a device of the class described, the combination with a lamp bracket hating a` horizontal arrn with a longitudinal opening through it, a contact' pin normally projecting'beyond the outer end of the` horizontal arm and insulated therefrom, a wire `electri cally connected. with said pin and extending through said arno, of? a lamp having a socket at its upper end adapted to set onto the hori- 'zontal arrn et the bracket whereby the lamp is supported, said lamp including a sleeve insulated from the lamp bodybut electricall connected with one pole of the lamp, saidyslee'v'e adapted `to contact with the contact pin carried by the bracket.

2. In a device of the class described, th'e combination with a bracket having an openend of said bracket beyond which it projects and from which it is insulated, a wire connected with said pin and extending through said bracket, of a lamp adapted to be supported by said bracket, one pole of the lam` being through the body of the lamp and sai through the lamp body and to the" 4 "ward in position to be engaged by the said .body and electrical? connected with one lng witnesses. poleof the lamp, sai contant projecting upf bmolmgland a Contact 'insulated from the specification in the presnce of two subscrib- GoRDoN WILLIAMS 5 contact im when the lamp is engaged with Witnesses:
